Prepaid water meter for purified water

Prepaid water meter for purified waterWorking Principle:

This series of water meters is an instrument used to measure the total volume of water flowing through the tap water pipeline. Through the settlement management mode of first payment and then use, it has changed the traditional meter reading and payment method for water use. Through contactICAs a medium, the card inputs various information into the control system of the meter, enabling the meter to automatically open the valve and supply water according to the water purchased by the user in advance. When the water volume reaches the alarm value or runs out, the valve will automatically close, interrupting the water supply, and the LCD display will prompt the user to purchase water, achieving prepayment control; It can also record the operation status of the transmission table, display the operation status of the table through a microcomputer under the system management software, and effectively monitor it, thus changing the past arrears of water fees, saving manpower, material resources, and financial resources of property management and water supply departments, and improving management efficiency. The base table of this product adopts a self-developed small movement structure and low torque ball valve, which has the characteristics of high sensitivity and low valve opening torque; Advanced microprocessors are used in the circuit to make the water meter havehigherThe performance of anti-interference, reliability, high precision, and low power consumption; Its structural design is compact and aesthetically pleasing.
